FREDERICK W. SCHMIDT, OF PHILADELPHIA, PENNSYLVANIA.

SLIDE FOE PROJECTINGLANTERNS.

To all whom it may concern:

Be. it known that I. Fnnnnnrcii W. ScHMm'r, a citizen of the United States, residing in the city and county of Philadeh phia, State of Pennsylvania, have invented a new and useful Slide for Projecting Lanterns, of which the following is a specifica- 131011,

My invention-relates to. a novel slide which is especially adapted to be employed for advertising purposes.

My invention comprehends a novel construction and arrangement of a slide for pro" jecting lanterns wherein the entire scene on theslide'or a portion of the scenery or advertising matter on-the slide is movable during the prQjectiOn of the picture.

It further, comprehends a novel construction and arrangement of a slide wherein.

means are provided toeifect the mechanical movement of any desired portion of the slide, such as for example can be obtained by means of a fluid in motion or by a mechanicalor other connection to, the parts which are to be moved. v i

Other novel features of construction and advantage will hereinafter more clearly appear in the detailed description of my in vention.

c For the purpose of-illustrating my invention, I have shown in the accompanying drawings forms thereof which are at present preferred by me, since the same will be found in practice to give satisfactory and reliable results, although it is to beunderstood that the variousinstrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents in perspective a projecting lantern, in conjunction with which is employed a slide embodying. my inven tion.

Figure .2 represents in front elevation a slide embodying my invention.

, Figure 3 represents a sectional view of the constructionseen in Figure 2, the section be ing taken on line 3 -3 of Figure 2.

Figure 4 represents in side elevation a projecting lantern in conjunction with Specification of Letters Patent. P t t Fail 14, 1922,

Application filed April 17,

1920. Serial No. 374,526.

Figure 11 represents a detail of the construction seen in Figure 9. 7

Similar numerals of reference indicate corresponding parts.

Referring to the drawings Referring first to Figure 1, 1 designates a projecting lantern of any desired or conventional type in which is placed a slide 2 which consists of a spring wound mechanical figure so that the picture projected therefrom on the screen 3 will have certain parts thereof in motion during such projection. A spring wound mechanical dancing figure is illustrated showing in dotted lines the position which the legs assume when dancing.

In the embodiment shown in Figure 2, the slide consists of a casing or framework a having an internal chamber 5 with which communicates a pipe 6, which as seen in Figure 4, leads from a blower or air compressor 7, which latter is driven by means of a motor 8 of any desired type, such as for example an electric motor. The scenery on the slide consists of a scene 9 which includes a wind mill, the vanes 10 of which are mounted. on a shaft 11 which extends through and is mounted in the rear end of the slide 4 and such shaft 11 is provided with a pulley 12 around which passes a belt 13 which also passesv around a pulley 14 carried by the shaft of the motor 8. blower or air compressor 7 is provided with an inlet into which powder, cut paper or other material may be inserted so that it may blow through the pipe 6 into the chamber 5 and will be circulated in the chamber 5 to simulate a snow scene, in which case the front of the slide 4 will be covered by a transparent plate 15.

In Figure 3 for purposes of: illustration, I have shown the material blown into the chamber 5 as collecting at the bottom of such chamber as at 16.

In the embodiment seen in Figures 2 to 4 inclusive, the movable part of the slide is mechanically moved by means of a connection from a motor, while in the embodiment seen in Figures 5 and 6 the air coinpressed by the blower is utilized to effect the motion of movable parts of the scene on the slide.

In the embodiment seen in Figures 5 and 6, a motor driven air compressor 17 isillus trated, which discharges into a pipe. 18, which latter is provided with a desired num ber of discharge ports 19, which are so located that they communicate with ports 20 opening into the casing 21 of the slide. In this slide seen in Figures 5 and (3, I have shown as a part of the scenery a flag 22.

During the projection of the picture, the flag will be waving due to the current of air passing into the slide from one of the ports 20. In this slide, I have also shown the vanes 23 of a wind mill, the vanes being in motion during the projection of the picture. I have also shown in this figure a clock 55, which is spring wound so that the hands will be in motion during the projection of the picture. I have also shown at the bottom of the slide in front of the scene thereon a track 24 which is endless and extends around in back of the scene, so that the air discharging from the ports 19 and blowing against the sails o1 a boat 25 will cause the boat to travel around the track 24 in front of and in back oi the scene. The boat 25 has secured to its bottom a guide member 26 which maintains the boat in assel'ubled positionwith respect to its track 24-. The casing 21. is provided with an exhaust port 27.

In the embodiment seen in Figure 7, I have shown a slide having a framework 28 on which are mounted rolls 29 having the blades 30. so that the rolls 29 will be revolved due to the air from the discharge ports 31 ot the pipe 32 impinging against them. The pipe 32 is in communication with the motor driven blower l? which in Figure 7 is shown diagrammatically.

designates a stationary portion of the scenery. such as for example, an automobile, which is carried by a support 34 and the wheels 85 of the automobile are rotated by means of compressed air discharging from the ports 36 and. impinging against the wheels of the automobile or other vehicle. It will be seen that in this embodiment the main portion of the scenery is moved by means of compressed air and a portion of the scenery stationary but is provided with movable parts.

From the embodiment seen'in Figures 9 and 11, the slide 37 is provided with a'framework in which is rotatably mounted the rollers 38 around which passes an apron 39 on which the scene which is to be projected is In this embodiment the vehicle is-stationary but the wheels are mechanically revolved during the revolution of the endless apron 39 which forms the body portion of the slide. In the embodiment seen in Figure" 10; I have shown a slide 48"having an internal chamber 49 inwhich is rotatable a slide proper 50 which passes around the roll'having a shaft 51. intergeared with a shaft 52 which carries a figure 53 one of the gears of the interconnecting gearing being provided with a handle 54 whereby the slide can be employed as a toy sothat a portion of the scenery can be in motion or it can be employed as a slide in which case during the projection of a picture the operator causes a portion of thedesign on the slide to be in motion. It will now be apparent that in accordance with my present invention thescenery on the slide either in whole or in partcan be mechanically driven by a positive connection or by means of fluid under pressure or manually operated during the subjection of the picture. Certain portions of the picture can be stationary or all of the picture can be in movement with certain parts or objects moving at different speeds or in diflerent di motions. It will of course be understood that the different scenes employed to illustrate the principle of my invention and the different moving objects employed are typical. only and that any desired arrangement of any objects. pictures or scenery can be employed.

Itwill now be apparent that]: have devised a novel and useful construction of a slide For projecting lanterns which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description. and while I have, in

the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character stated, a slide for projecting lanterns having a closed chamber within which the scenery is positioned said scenery including a movable part, a motor driving said movable part, and an air compressor driven by said motor and communicating with said chamber, whereby material can be circulated within such chamber in front of the scenery to simulate a snow scene.

2 The combination with a projecting lantern, of a motor driven air compressor, a slide having ports through which air from said compressor is discharged and having movable objects forming a part of its scenery, said moving objects being actuated by the air.

3. In a device of the character stated, the combination with a slide having a stationary frame-Work and a scene rotatably carried by it, of a stationary object carried by said framework and having movable parts, and means to actuate such movable parts during the projection of the picture.

4. A slide for projecting lanterns, comprising a casing having an endless track, a scene in rear of said track, and an object co-operating with said track, in combination with means to effect the movement of: said object on said track during the projection of the picture on the slide.
